Why are you bothering to look at $! here?
>#!/usr/local/bin/perl
> printf "Hello World\n";
> printf "ERRNO: %d\n", $!;
> use lib "$ENV{RTM_HOME}/rtm/src/vtm";

That 'use lib' line is happening FIRST, because 'use' happens at
compile-time, and the rest of your program happens at run-time.
But WHY ARE YOU LOOKING AT $! here? There's no reason to. $! has no
meaningful value unless something has gone wrong. Nothing has gone wrong,
so don't worry about it.
